Ceramic Filters (CERAFILr)/Ceramic Discriminators for Communications Equipment CERAFILr Plastic Case Group Delay Flat Type CFWLA_Y Series CFWLA_Y series are high selectivity ceramic filters, which consist of 6 ceramic elements connected in a ladder form. Most suitable for digital communications and mobile telephones because of their improved GDT characteristics. s Features 1. High selectivity. 2. A variety of bandwidths are available. 3. Excellent GDT characteristics are available within pass bandwidth. 4. Easily mounted on a printed circuit board 5. Operating temperature range : -20 to +80 (degree C) Storage temperature range : -40 to +85 (degree C) 0.15 2.3 ±0.3 2.0 ±0.3 2.9 ±0.3 11.0 ±0.5 1.2 ±0.5 (1) (2) (4) (3) (5) 0.6 ±0.1 0.8 ±0.1 2.6 ±0.3 2.9 2.9— —0.3 0.3 2.9 ±0.3 Type CFWLA455KB4Y-B0 CFWLA455KC4Y-B0 CFWLA455KD1Y-B0 CFWLA455KE1Y-B0 CFWLA455KF1Y-B0 CFWLA455KG1Y-B0 Marking BY CY DY EY FY GY Connection (1) : Input (2) (3) : Ground (4) (5) : Output (in mm) } MARKING EIAJ CODE Part Number Center Frequency (fo) (kHz) 6dB Bandwidth (kHz) Stop Bandwidth (kHz) Stop Band Attenuation (dB) Insertion Loss (dB) GDT Deviation ( µs) Input/Output Impedance (ohm) CFWLA455KB4Y-B0 455.0 ±1.5kHz fn ±15.0 min. fn ±35.0 max.

[within fn ±3kHz] 2000 For safety purposes, connect the output of filters to the IF amplifier through a D.C. blocking capacitor. Avoid applying a direct current to the output of ceramic filters. (fn) means nominal center frequency 455kHz. The order quantity should be an integral multiple of the "Minimum Quantity" shown in package page in this catalog. s Test Circuit E1 R1 R2 E2 RF Voltmeter Connection (1) : Input (5) : Output (2)(3)(4) : Ground Rg S.S.G. 0dBm (1) (2) (3) (4) (5) Rg+R1=R2=Input/Output Impedance Please read rating and !CAUTION (for storage and operating, rating, soldering and mounting, handling) in this PDF catalog to prevent smoking and/or burning, etc. This catalog has only typical specifications.
